In this photo made with a fisheye lens on Tuesday, Jan. 15, 2013, five used military style rifles are all that is available in the rack that usually has over twenty new models for sale at Duke's Sport Shop in New Castle, Pa. Store manager Mike Fiota says the few there are on consignment from individuals. President Barack Obama is expected to announce measures Wednesday, Jan. 16, 2013, on a broad effort to reduce gun violence that will include proposed bans on military-style assault weapons and high-capacity ammunition magazines as well as more than a dozen executive orders aimed at circumventing congressional opposition to stricter gun control.
